Recently I bought a couple of old Mamiya RB67 lenses to use with a Fotodiox adaptor on my Nikon D800E. This is one of the first shots I took with the 127mm f/3.5 lens.
This particular part of Shinagawa, down towards the Konan Exit of the JR railway station, has some amazing light towards the end of the day; streaming in from the large windows at the top of a large atrium in the building.
Great spot to shoot with the backlight at that time of day.
This lens setup is not light but it produces some great results.
